AUTOMATIC MACHINE FOR FORMING BAGLE-DOUGH RINGS Louis Gendler, New York, and Morris Lazar, Jamaica, N. Y., assignors to American Bagel Machine Co., Inc., New York, N. Y., `a corporation of New York Application September 30, 1948, Serial No. 51,886

Our invention relates to an automatic machine for forming dough rings for making bagles. The primary object and purpose of this invention is to provide a machine which is operable automatically to produce rings of bagle shape from a mass of bagle dough. Heretofore, so far as we are aware it has been necessary for bakers to produce such rings by manual operations, and ralthough attempts have been made prior to the 'present invention to provide a machine for mak- Iing such rings, such attempts, so far as we are aware, have been unsuccessful.

The above and other objects of the invention aswell as objects ancillarythereto will be fully understood from the following descriptionconsidered in connection with the accompanying drawings which, however, are to be consi-dered as illustrative of our invention but not inv limitation thereof. f

As is well known, a bagle is similar in shape to a doughnut, being in the form of aring having a circular cross section. However, due primarily to the fact that bagle dough prepared according to they usual recipe is comparatively stiff, the bagle ring cannot be formed directly from the dough, as in the case of a doughnut or other pastries, but requires several operations for the formation thereof. More particularly, in order to form a bagle ring from bagle dough it is necessary first to separate a piece of ldough of predetermined size from the batch of dough and to shape said piece of dough into a generally cylindrical form, and then to shape the cylindrical piece of dough into the bagle ring. These operations are performed automatically by the machine of the present invention.

Referring now to the drawings in details, the machine embodying the present invention comprises a rigid frame l0 supporting a dough eX- trusion device l2 and a companion cutting device l4, which operate together to produce a piece of dough in apreliminary shape and of the predetermined size required for forming the bagle; a shaping device l5 which forms said piece of dough into cylindrical shape; a device I8 which includes a former frame 22 and an endless conveyorl 29 to receive the cylindrical piece of dough in such manner that it automatically,

by gravity, assumes the form of an inverted U (Fig. 8) and conveys said piece of dough to a device which includes the companion rollers 24, 26 and the endless belts 28, 3l! which engage the free endsof the piece of dough and press them together (Fig. 9); and a rounding device 32 which receives the endless piece of dough and rounds the same into circular form. The frame I0 also supportsother parts of the machine which will be subsequently referred to in the more detailed description of the machine, including the powerdriven mechanisms of the machine.

The extrusion device I2 comprises a casing 34 having a hopper inlet 3B and a dough-shaping outlet-cap 3B which is preferably, as here shown,

. removably 'secured` to casing 34 in any suitable way as by ay plurality of Ascrews 40. The outlet opening 42 of cap 38 is of generally oval shape as shown by Figs. 3 and 10. An inclined board 44 is provided for convenience in delivering the dough to the casing of the extrusion device I2.

A rotary extrusion screw 46 is disposed within casing 34 for expressing the dough, in the preliminary shape. through the outlet opening 42.

accesos distance onto the belt, be in a position in which yit is inclined lengthwise, or otherwise-improperly positioned, in relation to the direction of movement of belt |28. This diiculty is obviated by locating the outlet opening 42 close to the upper surface of said belt and the dough-piece Bl necessarily is deposited in the correct position as hereinbefore described.

Conveyorl belt |28 is power driven by motor 98 through reduction gearing in timed relation :to the operation of cutting device I4. For this purpose the gear |04 on drive shaft |02 is connected by gear |54 to arotary shaft |50- journalled for rotation in suitable bearings |51. A A housing |59 (Fig. 1) is provided for said shaft and gears carried thereby. Shaft |56 isconnected by gears |50 and |60 to a shaft |62-(Figs. 2 and 5). Said shaft is connected by a sprocket chain |64 to a sprocket gear |68 for driving the front roll |68 by which endlessk belt |28 is driven. The roll for'the opposite end of belt |28 need not be driven. kIt will be understood that rolls Y|68 and |10 are rotatably mounted in suitable bearings in frame l0. It will be noted lthat the upperV run of'belt IZBpasses over a'rigid plate |12 so that said upper run of the vbelt is held firmly aganist downward displacement particularly during the action thereof in conjunction with member |30 for rolling and shaping the dough-piece BI into the cylindrically vshaped and elongated piece B2.

. rIhe shaped dough-piece B2 is moved by belt |28 to the adjacent end of the .device |8 where said dough-piece drops onto conveyor belt of said device and assumes the invented U-shape shown at B3 in Figs. 7 and 8. When the doughpiece B3 moves betweenthe endless belts 28 and the ends of said dough-piece are pressed together forming the somewhat elliptically shaped dough-piece B4 as shown in Figs.l'1 and 9. Downwardly inclined members |14, which` are secured to frame 22 in any suitable manner, are positioned adjacent the forward'end of the upper run of belt |23 for guiding thedough-piece B2 onto the upper run of endless conveyor 20. Conveyor 20 is here shown as a sprocket chain and is driven by a sprocketY gearv |15 xed to shaft |02. Said sprocket chain passes over the idler gears |18, |80, over the front guide roll |82 and over the idler sprocket gear |84. Pulleys 24 and 25 which drive endless belts 28 and 30 are driven by vertical shafts |86 and |88 respectively (Fig.

`6) which are in turn driven by a shaft |00 operatively connected to shafts |88 and |83 by gears |02, |94 and |96, |98, respectively.y Shaftg|90 is 'driven by shaft F56 through gears 200 and 202. vIt will be understood that through this gearing and pulleys 24 and 26, belts 28y and 30 are driven at the same linear speed as' conveyor 20. As illustrated in Figs. 1 and 7 idler pulleys 204 and 206 are provided in conjunction 'with pulleys-24 `and 2e for endless belts 28 and 30, respectively. Provision is made for applying flour or other substance to prevent the dough from sticking to belts 28 and 30.

are engaged by said belts, respectively, and are thereby rotated.

TheV rounding device 32 is positioned at the delivery end of conveyor`20 (Figs. l, 2 and 7).

4Said roundingy device includes a rod 208, the -upper end of which tapers upwardly as indicated For this purpose our containers '201 and companion rotary brushes 209 are pro- 6 at 2| 0, the remainderl of said rod being cylindrical. Said rod 208 is carried by and depends vertically from'the' forward end portion 2|2 of longitudinally extending frame 22 in which the upper run of conveyor 20 extends. When the dough-piece B4 reaches said end 2|0 of frame 22, the dough-piece moves downwardly around rod 208 into the rounding device 32. n order to obviate the possibility of any of the dough-pieces B4 failing to drop down around rod 208, provision is made for positively moving said doughpieces oil the forward end of conveyor 20. The means which is provided, as here shown, for this purpose `comprises the disks 2| 4 and 2|8 carrying circumferentially spaced blades 2| 0 which are positioned to strike the dough-piece B4 lightly when the latter is at the forward end of frame 22 whereby tol vpush said dough-piece 01T said end of the frame so that it may drop into rounding device 32a-around rod 208. It will be noted that disks 2|4 and 2| 6 are vdriven by the belts 220 and 222, respectively, actuated by pulleys 224 and228 which are driven by shafts |88 and |88.

The rounding device 32l includes a tube 221 supported on frame I0 by brackets 220. A plurality of endless belts, there being four of such belts 228, 230, 232 and 234, extend vertically and are arranged in generally circular form around rod 208. Said belts pass vertically into and out of'tube 221 and are arranged so that the inner runs of said belts are close to the inner peripheral surface of said tube. VEach of said belts is preferably formed of sheet material such as canvas or other closely woven and durable fabric rsprocket wheels 240 are supported for rotation but are not driven except through the companion sprocket chains 238, respectively. Referring to Fig. 5 and in conjunction with Fig. 2, it will be noted that sprocket gears 238 are operatively connected to each other for movement in unison. A driving shaft 242 isactuated by shaft |58 throughV gears 244 and 246 for rotating said sprocket gears 238. Shaft 242 is geared to the sprocket gears 238 of conveyors 228 and 234 between bevel gears 248, 250 and 252. Sprocket gear 238 of conveyor 230 is geared to sprocket gears 238 of conveyors 228 and 232 by the bevel Y'gears`254, 258 and 258, 260, respectively. It will be understood that the flexible belts of the conveyors 228, 234 are disposed around rod 200 and are of such width that their adjacent edges are in abutting relation throughout the inner vertical runs of said flexible belts, except at the upper and lower ends of tube 221, so that the ymajor portions of theinner vertical runs of the flexible belts dene a generally cylindrical tube around rod 203. As the inner runs of these belts move downwardly, as indicated by the arrows in Fig. y2, they carry with themfthe dough-piece B4 for rounding the latter into its circular ring form. In this rounding operation, the portions of the dough-piece B4which were pressed together by belts 28 and 30 as above described with particular reference to Figs. 7 and 9 are smoothed into the circular rounded body of the dough-piece. The completely formed dough-piece issues from the bottom of the rounding device 32, as indicate-d at B in Fig. 2 and as here shown said doughaccuses .piece` drops onto a1-fconveyor.252,-for delivery to anysuitable.point,as, will be' readily understood.

Itv will. be. understood, that. after the. rounded doughfpieces B are-formed, they are; cooked and baked: in Vaccordance with the usual method of making bagles.

Thus it is seen that the machine of the present invention is operable automatically to form bag-le rings from ai mass of bagle dough without requiring* any handling of the dough or any manual operation thereon throughout the process oi separation of thev dough pieces from the mass of dough to the end of the ring-forming operation. It will be understood that various changes may be made without departing from `the underlying. idea of the invention within the scope of the appended claims.

Having thus -described our invention, what we claim andk desire to-secure by Letters Patent is:
